WHENGl-ll Specification of Letters "Patent.

Patented Aug. 15, 1995.

Application filed October 17, 1904. Serial No. 228,694.

To will whom it may concern:

Be it known that I, ERNEST T. Fos'rnn, a citizen of the United States,residing at VVinterset, in the county of Madison and State of Iowa, haveinvented a certain new and useful V french, of which the following is aspecification.

The objects of my invention are to provide a wrench adapted for use inremoving a particular form of nut and bolt forming a vehicleaxle and soarranged and constructed that the nut and the bolt will be removed fromthe axle simultaneously by the use of this wrench.

It is more particularly my object to provide a wrench for use inconnection with a lock-nut for vehicle-axles which is in vented by meand for which I have made an application for Let-, ters Patent of evendate herewith.

ltiy wrench is of simple construction and is adapted. for use on nuts ofvarious sizes and in di'lierent ways, and it is so arranged that bysimply turning the handle of the wrench a bolt which extends through thenut on a vehicle-axle will be unscrewed, and at the same time the nutwill be drawn downwardly by the wrench as the wrench is being turned.

My invention consists in certain details in the construction,arrangement, and combination of the various parts of the device, wherebythe objects contemplated are attained, as

' hereinafter more fully set forth, pointed out in my claims, andillustrated in theaccoxnpanying drawings, in whichltigure 1 is asectional view of a portion of a vehicle-axle and a portion of the hubof a wheel with a locked nut thereon, showing in sectional detail mywrench and the way of attaching .it to the lock-nut for securing thelock-nut or removing it from the axle. Fig. 2 is an end view of the axlewith the hub of a wheel thereon, showing a plan view of my wrench; andFig. 3 is a detail perspective view of the outer end of my wrench.

Referring to theaccompanying drawings, l have used the reference-numeral10 to indicate the handle of the wrench. This handle has a series ofopenings through it of different sizes adapted to receive bolts ofvarious sizes, as in the ordinary wrench.

The reference-numeral 11 indicates the head of the wrench having anopening 12 extending through it. On the interior of the head of thewrench is a recess 13, communicating with the opening 12, which isslightly larger than said opening and is designed to form a circularshoulder 14:, against which the head of the bolt to be unscrewed rests.The head of this bolt also engages the sides of the opening13 while thewrench is being used. At the extreme outer end of the head of the wrenchis a jaw 15, the body of which extends at right angles to the head ofthe wrench and has the extension 16 at right angles to the body of thejaw and substantially parallel with the head of the wrench. Thisextension is designed to engage an annular rim on the nut which is to beremoved. At the opposite end of the head from the fixed jaw 15 is apivoted jaw 17, which extends through the handle 10 and a slightdistance from the opening 12 through the head. This pivoted jaw has theextension 18 extending outwardly from it and substantially at rightangles to it toward the jaw 15. This jaw 17, with its extension 18, isdesigned to engage one side of the nut, while the jaw 15, with theextension 16, engages the side of the nut which is diametricallyopposite. The pivoted jaw has a thumb-piece 19 extending away from thepivot 20, which holds the pivoted jaw 17 to the handle 10, and securedto the head 11 and resting against the thumb-piece 19 is a leaf-spring21, which normally holds the pivoted jaw at its limit of movement towardthe fixed jaw, so that after the jaws have been placed upon the annularrim of the nut which is to be removed the wrench is held in positionrelative to the nut by means of the spring 21 acting in conjunction withthe jaws. in the use of my wrench it is necessary to have aslidingly-mounted non-rotatable nut 22 and a screw-bolt 23 passedthrough the nut 22 and into the axle upon which the nut is mounted insuch a way that the head 2% of the bolt extends outwardly from the outersurface of the nut, and there must also bean annular riin 25 on theouter end of the nut 22, which is to be engaged by the jaws l5 and 17.

in practical operation the pivoted jaw 17 is swung to its extreme limitof movement away from the fixed jaw 15 by pressing outwardly on thethumb-piece 19. The fixed jaw is then slipped over the annular rim 25,and the ban dle of the wrench is moved inwardly toward the nut in such away that the head 24 of the bolt 23 enters the opening 13 and restsagainst the shoulders 14 in the head of the wrench. The thumb is thenremoved from the thumbpieee 19, and the spring forces the jaw 17 intoengagement with the annular rim 25 at a point diametrically oppositefrom the position of the jaw 15 on said wrench. Assuming that the nut issecured to the axle, the operator turns the wrench to unscrew the bolt,and as he does this the jaws l5 and 17 will slide around on the annularrim 25 of the nut, and as the bolt is unscrewed by the wrench the nutwill be drawn outwardly and removed. The wrench will maintain the boltand nut in position relative to each other while they are removed, if itis desired, by the operator, and by simply repeating the operation ofremoving the nut, except for screwing the bolt into the axle, the nutcan be replaced and held rigidly in position to the axle by the use ofmy wrench.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States therefor, is

1. A wrench capable of turning a bolt, comprising a handle, a head atone end of the handle, means for securing the wrench to the head of thebolt and rotatably securing the Wrench to a nut so that as the wrench isturned in one direction, the nut will be drawn outwardly, and as thewrench is turned in the opposite direction the nut will be moved in-Wardly.

2. In a wrench, a handle, a head at one end of the handle, a fixed jawat one side of the head, a pivoted jaw at the other side of the head, aspring for normally holding the pivoted jaw at its limit of movementtoward the fixed jaw, an extension on the fixed jaw extending toward thepivoted jaw, and an extension on the pivoted jaw extending toward thefixed jaw, for the purposes stated. 4

3. In a Wrench, a handle, a head at one end of the handle having anopening in it designed to receive the head of a bolt, and jaws connectedwith the head designed to engage a nut and hold the nut and bolttogether while using the wrench and when the bolt and nut are removed.

4;. In a wrench, a handle, a head at one end of the handle, having anopening extending through it and a recess therein designed to receivethe head of a bolt, jaws connected with the head, designed to engage anut for holding the nut and the bolt together while the wrench is beingused.

5. In a Wrench, a handle, a head at one end of the handle, having anopening extending through it and a recess therein designed to receivethe head of a belt, a fixed jaw at one end of the head having anextension at right angles to its body portion, and a pivoted jaw securedto the head at a point adjacent to the handle, having an extension atright angles to its body portion projecting toward the fixed jaws.

6. In a wrench, a handle, a head at one end of the handle, having anopening extending through it and a recess therein designed to receivethe head of a belt, a fixed jaw at one end of the head having anextension at right angles to its body portion, a pivoted jaw secured tothe head at a point adjacent to the handle, having an extension at rightangles to its body portion projecting toward the fixed jaws, and athumb-piece on the pivoted jaw, for the purposes stated.

7. In a wrench, a handle, a head at one end of the handle, having anopening extending through it and a recess therein designed to receivethe head of a belt, a fixed jaw at one end of the head having anextension at right angles to its body portion, a pivoted jaw secured tothe head at a point adjacent to the handle, having an extension at rightangles to its body portion projecting toward the fixed jaws, athumb-piece on the pivoted jaw, and a spring for normally maintainingthe pivoted jaw at its limit of movement toward the fixed jaw.
